To quickly build a human-readable random string for a captcha per example :
<?php
function random($length = 8)
{
$chars = 'bcdfghjklmnprstvwxzaeiou';
for ($p = 0; $p < $length; $p++)
{
$result .= ($p%2) ? $chars[mt_rand(19, 23)] : $chars[mt_rand(0, 18)];
}
return $result;
}
?>
Note that I have removed q and y from $chars to avoid readability problems.
